STILLWATER - A judge today ruled in favor of Mayor Nathan Bates, saying the mayor's use of a city computer to send e-mails for personal business was not a felony crime. A prosecutor said he will appeal the decision by Payne County Special Judge Phillip Corley. Bates, an Oklahoma State University graduate student, remains free on bond. He said prosecutors are wasting taxpayers' funds by appealing. Bates is charged with violating Oklahoma's computer crimes law. He would have faced trial if the judge had ruled against him.
